What to read after Light in the Shadow Lands?

Twenty-five years ago rumors began to circulate that all was not well in the literary world of C. S. Lewis. Lewis's brother vehemently denied false claims made by those who control the C. S. Lewis literary estate but bogus Lewis literature began to appear in print anyway.
Since Lewis's books still sell in the millions, powerful forces have been exerted to keep this controversy from surfacing. Author Lindskoog has spent 20 years unearthing old evidence and compiling new data that Martin E. Marty calls "compelling," adding that he hopes Lindskoog "will be heeded." Instead, within weeks of being released, her book's original publishers yielded to pressure and silently dropped it from their active list.
Willard Dickerson, Jr., director of education and professional development for the American Booksellers Association has stated, "I am surprised that so many who love the writings of C.S. Lewis have chosen to remain deliberately silent or to suppose the evidence they have that his writings have indeed been tampered with. I can vouch for Kathryn Lindskoog's scholarship, integrity and clear thinking. Her facts ring with truth." An array of famous authors, including Arthur C. Clark and Ursula K. LeGuin have joined the chorus of those who recommend her "fascinating," "astonishing" and "exciting" book. Therefore we have determined to re-release this extraordinary piece of literary scholarship.
